Specification of Letters Patent.

Patented March 12, 1907.

Application filed July 14,1905 Serial No. 269,641.

To (d7 whom it may concern."

Be it known that I, EGBERT H. GOLD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Couplings, of which the following is a specification.

My invention relates to improvements in couplings for fluidconduits, and is particularly and primarily intended for use in hosecouplings on railway-trains.

The object of my invention is to provide such a coupling of simple construction, wherein a suitable gasket may be readily seated and removed.

Another object of my invention is to provide such a coupling wherein the gasket may be reversed.

These and such other advantages as may hereafter appear are attained in my invention, a typical embodiment of which is shown in the drawings, in Which Figure 1 is a longitudinal sectional View through a coupling andgasket. Fig. 2 is a view on the line 2 2 of Fig. 1 looking in the direction indicated by the arrows. Fig. 3 is a sectional view .of the coupling with the gasket being inserted. Fig. 4. shows the gasket in front elevation. Fig. 5 is a side elevation of the gasket. Fig. 6 is a view on the line 6 6 of Fig. l looking in the direction indicated bythe arrows-'- Fig. 7 is a longitudinal sectional view through the coupler without thegasket. Fig.8 is a longitudinal sectional view of a modification. Fig. 9 is a view on the line 9 9 of Fig. 8 looking inthe direction indicated by the arrows.

Like letters of reference indicate the same parts in the several figures of the-drawings.

Aindicates the body of a coupling, which for purposes of .illustration is shown as of the familiar Sewall type, and is provided with a coupling-arm B, having a locking-lug C, and on the opposite side is provided with a locking-lug D.

Y E is the nipple.

F indicates the fluid-passage, and G the gasket.

When my invention is embodied in the form shown in the drawings, the gasket G forms a section of a s here cut away on opposite sides to form t e flat faces 9 and g.

. The coupling is provided with a concave seat adapted to receive the gasket, as shown in Fig. 1, and the opening in the face of the coupling A is cut away at ac, so as to receive the gasket when inserted edgewise. 'lo seat the gasket in the coupling, it is inserted edgewise into the gasket-seat, as shown in l ig. 3, whereupon the gasket is given a quarterturn until it assumes the position shown in Fig. 1, in which position the gasket will be securely held in the coupling by the overhanging edges a, a, while the gasket, will project slightly from the face of the coupling, as shown in Fig. 1, so as to engage the corresponding gasket on the opposite coupler. To remove the gasket, it is only necessary to reverse the operation by giving the gasket a quarter-turn until it can be withdrawn edgewise through the cut-away portions a a, while, if desired, the gasket may be reversed after the face 9 has beenused, so as to cause the face g to project. If for any reason it be not desired to have the gasket reversible, the face 9' of the gasket may be dispensed with, as shown inliig. 8, the rear face of the gasket rounding until it intersects the fluidpassage through the gasket, in which event the entire back of the gasket will rest in contact with and be supported by the body of the coupler, thus giving a solid support or backing for the entire face g.

While I have shown the invention embodied in its preferred form, it should be understood that the contour of the gasket and gasket-seat may be varied so long as the principles of construction and operation above set forth are adhered to. i
